CIM's don't necessarily run too hot. Our drive motors don't have heat sinks. I haven't seen a single one overheating. However, that could be because we are using mecanum so the motors keep moving even if the robot is stalled, another pro for mecanum! |
I think you are thinking of the "Ice Box" for 775 style motors. That is a powered fan and full enclosure for the motor.
The CIM cooler is just an aluminum heat sink that attaches on to the outside of a CIM motor. It will definitely make it easier to remove some heat by adding surface area, but it also takes up some space and weight. We have never needed to cool our drive motors and have never noticed a loss of power from not doing so. However, there could be some advantage to it if you were dependent on consistency in drive (i.e. moving forward for a set time in autonomous rather than using encoders). That being said, our CIMs get hot to the touch and taking some heat off of them is on our list for this year, just not very high on that list.
Honestly we might just use a few of the fans out of our pile of collected fans if we have time.
